The late Alfred Lagarde performed the original voice of Telly on Sesamstraat, the Dutch co-production of Sesame Street.
After a few brief appearances, Telly became a main character in the late 1980's. His Dutch name is Teevee Monster, or simply Teevee ('tay-vay').
When Alfred passed away in 1999, Fred Meijer became the new Telly.
